A few questions that came to mind while reading:
Why cant you show off your toned female body?
Is pregnancy really that much of a hassle as in limitation to your life? 9 months of people being extra nice to you, and most of the time it wont affect you in a REALLY restrictive way.
Why cant you be in the gym a lot working on your body to improve your health and make you more attractive as a mate as a woman?
Why cant women wear practical clothes/ wear short hair and still look decent?
Why cant you try to find other women who're interested in sport?
Now my male perspective:
Working on my body is tedious and annoying, an opinion I could easily get away with as a woman, not so much as a man, and for good reason: As a woman you usually dont even need to work out to be considered attractive, just dont be fat. About pregnancy... thats a hassle for us too, it only takes 1 mistake to fvck your financial life up quite a bit as a man, same for women, but for you its a lot easier to avoid, and even if you fail at contraception you can abort, men cant do that (Also: You may view pregnancy as a hassle now, but that opinion will change once you get involved in legal disputes concerning your children.). The clothes/hair thing is the same for men, just for us its long hair we "cant have". Not every woman is interested in clothing, hair, children, not every man is interested in sport (fyi). Men lose "sexual value" with aging aswell, if you belong to those with sh1tty, rapidly disappearing hair (me) its even faster than women. Lastly: As a man i can assure you: We cant do as we want into our 50s and then still have time to settle down and produce our children. Else everyone would be doing it, dont you think?
As you can hopefully see being male isnt the cure to all our woes and mortality. The stuff you complain about is barely gender-related, most not at all. Dont blame your failings as a human being on gender, doing so inevitably leads to suffering, despair, anger and hate and ultimately... feminism. Once you start down that path, it will forever dominate your destiny, it will consume you.
